SEAL-LOCK.

SPECIFICATION forming part of Letters Patent No. 620,846, dated March 7,1899.

Application liled March 14, 1898. Serial No. 673,764. (No model.)

To all whom t may concern.-

of the United States of America, residing at Denver, in the county ofArapahoe and State of Colorado, have invented certain new and usefulImprovements in Seal-Locks; and I do declare the following to be a full,clear, and exact description of the invention,such as Will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the igures ofvreference marked thereon, which form a part of this specification.

My invention relates to improvements in seal-locks, my object being toprovide a device of this class which shall be simple inconstruction,economical in cost,reliable,dnrable, and efficient in use;and to these ends the invention consists of the features, arrangements,and combinations hereinafter described and claimed, all of which will befully understood by reference to the accompanying drawings, in which isillustrated anemb'odiment thereof.

In the drawings, Figure 1 is a perspective view of my improved seal-lockin use. Fig. 2 is a side elevation of the device viewed from theopposite side, the slide being removed from the' lock-case to expose themechanism within. Fig. 3 is a top view of the device with the hasp-armdetached. Fig. Llis a section taken on the line @c Fig. 2. Fig. 5 is aperspective view in detail of the slide closing one side of thelock-case.

Similar reference characters indicating corresponding parts in theseviews, let the numeral 5 designate what Will be called inthisspecification the hasp-arm, which is provided at one extremity with aneye 5L,through which a staple 7 is passed for the purpose of securing itto the car-door 6 or other object. The opposite extremity of the arm 5is provided With a hook or depending projection 5c, adapted to pass through a staple 8, made fast to the side of the car 10, adjacent the door6. This hook 5C also passes through an opening 9, formed in a projection9c of the lock-casing 9. When the lock is applied, the staple 8 on thecar is located between the projection i); of tle lock-case and thehasp-arm 5. (See The lock-case is promwith a projection 94, formed onthe side opposite the projection 9. This projection is apertured toregister with an opening formed in a lug 5d on the hasp-arm 5. Thelock-case is pivotally connected with the hasp-arm by passing a rivet orpin 9g Ithrough the registering apertures of the projection 9d and thelug 5. Within this case is located a dog 12, pivoted thereon, as shownat 13, and supported by a leaf-spring 14. This dog is adapted to engagea hookshaped jaw 5h, rigidly attached to the hasparm and passing throughan opening 9h, formed in the top of the case.

The lock-case is slotted on one side, as shown at 9m. Through this slotprotrudes a lug 12a, formed on the dog 12. When this lug is exposed,.thedog 12 may be unlocked from the jaw 5h by pulling downwardly on the lug.When the parts of the mechanism are as sembled, the dog can only bedisengaged from the hasp-jaw through the instrumentality of this lug,which is concealedv by the breakable seal 15, carrying the number orother desired designation of the car or other object to which the lockis applied. This seal is inserted in vertical grooves or Ways A, formedin the sides of the case, and occupies a position in a vertical planejust outside of the lug 12 of the dog 12. The grooves A are open at thetop to allow the seal to enter and closed at the bottom to prevent itfrom dropping out.

When the lock-case and hasp-arm are connected by the engagement of thedog 12 and the jaw 5h, the upper edge of the lseal 15 is concealed by aiiange B, formed on the hasparm, which flange overlaps the top of thelock-4 case and prevents the removal of the seal. The lockcase is openon the seal side, Wherebythe number or other designation of the car orother object formed on the'seal is eX- posed. The opposite side of thelock-case is closed by a slide 16, whose edges are dovetailed to engagecounterpart grooves formed in the lock-case. The slide is inserted fromthe left-hand side, (see Fig. 2,) the grooves being openen this side forthe purpose. The slide is put in place before the hasp-arm and lock-caseare connected by the pivot-pin 9g, since after these parts are assembledthe lug 5d on the hasp-arm is located immediately in front of the slideand prevents its removal, the lug being curved to conform to the arc inICO which the case moves when the jaw 5h is disengaged from the dog 12.This slide closes the lock-case on the inside or the side opposite theexposed seal side and protects the operating parts.

In using the device, assuming that the parts are assembled in operativerelation, the seal being absent, the hasp-arm is first fastened to thedoor by the staple 7. The dog 12 is then disengaged from the jaw 5h bypressing downwardly on the lug l2, allowing the lockcase and hasp-arm toseparate, the case turning on the pivot-pin 9g. The seal 15 is theninserted, the hook 5 passed through the staple 8, and the lock-caseraised until its projection 9c engages the hook 5C of the hasparm andthe dog 12 engages the jaw 5h. It is evident that when the parts are inthis position the door can only be unlocked by breaking the seal andgaining access to the lug l2. The pivot-pin 13 passes through the slide16 and holds the latter securely in place. The projection 5C of thehasp-arm is provided with an opening 9S for locking or sealing by othermeans, as hooks, wires, tin seals, padlocks, orotlier devices.

Having thus described my invention, what I claim is l l. The combinationof the hasp-arm having a jaw, a lock-case pivoted on the hasparm, aspring-held dog located in the said case and adapted to engage the jawon the hasparm, a slide inserted in the lock-case and concealing the dogfrom the inside, the hasp-arm being provided with a lug located in frontof the slide when the parts are assembled and curved to conform to thearc in which the case moves, thus preventing the removal of the slide, asuitable seal inserted in the case outside of the dog and protecting thelatter from external access as long as the seal remains intact, thehasp-arm being provided with a flange adapted to close the seal-entrancein the lock-case.

2. The combination of the hasp-arm having an angular projection and arigid jaw, a lockcase pivoted on the hasp-arm and provided with anapertured projection through which the angular projection of thehasp-arm passes, a spring-held dog located in the lock-case and adaptedto engage the jaw on the hasp-arm, a slide mounted on the lock-case andconcealing the dog from the inside, the hasp-arm being provided with alug located in front of the slide when the parts are assembled andcurved to conform to the arc in which the case moves as it swings on itspivot away from the hasp, thus preventing the removal of the slide, asuitable seal inserted in the lock-case outside of the dog andprotecting the latter from eX- ternal access as long as the seal remainsintact, the hasp -arm being provided with a fiange adapted to close theseal-entrance in the lock-case.

In testimony whereof I affix my signature in presence of two witnesses.l
